10x-7y = -6
5x+7y = 81
Add both equations to eliminate y:
15x = 75
Divide both sides by 15 to find the value of x:
x = 5
Substitute the value of x into the original equations to find the value of y:
Therefore: x = 5 and y = 8
The ordered pair is (6, 3).
The ordered pair is (3, 2).
The ordered pair is (2, 3).
y = 3x =3(6) = 18 ... the ordered pair is (x,y) = (6,18)
Any ordered pair that satisfies y = 22 - X is a solution.
(3,3)
The ordered pair is (6, 3).
The ordered pair is (3, 2).
The ordered pair is (2, 3).
The ordered pair is (5, 4).
The ordered pair is (-1, -2).
The ordered pair is (-1, -7).
The ordered pair is (1, 1).
y = 3x =3(6) = 18 ... the ordered pair is (x,y) = (6,18)
